摘要： An image output apparatus for controlling an output image stably. The image output apparatus comprises a database for storing data giving a relation between manipulated variables and a controlled variable for a reference pattern. The apparatus estimates sets of values of the manipulated variables used when outputting an image of the reference pattern, by using the data on the database to obtain values of the manipulated variables from a desired value for the reference pattern. By means of detected values for a plurality of images of the reference pattern outputted according to the estimated values of the manipulated variables, set values of the manipulated variables for the desired value is calculated.

摘要： An image forming device in which the toner density of a two-component developing device can be stably controlled in printing a one-page image and the frequency of interruption of even printing a series of pages can be decreased as less as possible. The number of pixels of the image relevant to the development counted during the printing and the toner consumption is estimated from other image information, and the amount of toner corresponding to the consumption is supplemented. In this supplement, the count is acquired at an intermediate time of the one-page printing, the toner consumption is estimated, and the toner is supplemented during the printing after the intermediate time. Thereby, toner supplement can be performed ahead of its schedule, and a variation of the toner density can be prevented correspondingly.
